Watch This Unimpressed Dialect Coach Critique Famous Movie Accents

He even tries to pin down where Heath Ledger's Joker might be from, bless his soul.

Courtesy of the good nerds over at Wired, here's a video in which dialect coach Erik Singer praises and roasts a whole bunch of different actors' accents in various movies. Sure, the guy's burning all his professional bridges, but it makes for a great watch. Check it out:

Besides the appropriate savage burns levied at the likes of Nic Cage and Kevin Costner, there's some really fascinating stuff in here; he goes deep on Idris Elba's performance in Long Walk to Freedom. The acting itself was up to snuff, but so was Elba's attention to playing Mandela himself, which for any actor, not matter how good, can easily veer dangerously into "impression" territory.

Even Angelina Jolie gets her due for her weirdo passion project Maleficent, a film worth watching just for the sheer bizarre confidence of her performance alone. Singer says she chooses an accent that doesn't even exist anymore, if it ever did, but she nails the specifics (unlike good ol' Costner, who in today's Britain couldn't get a more than a couple of words out before being deported by Nigel Farage).

Singer goes through a whopping thirty-two accents here, and really does his best to span the globe: from Leo DiCaprio's West African (Blood Diamond) to Jon Malkovich's Russian turn in Rounders, which, c'mon man. Malkovich does what he wants.

There are bound to be more videos like this on the way, so start putting together your analysis wish-list now. Me? I'm just happy to have it confirmed Reneé Zellweger crushed it in Bridget Jones.
